638 General Notes, (July, 
The conclusion to be made is that the two species changed 
somewhat during the time which is represented by the bed of 
limestone. ` 
By the Geological Survey of Alabama there has been made 
out, by a series of profiles, that certain fossiliferous Tertiary beds 
are successional in age, for instance, that the Woods Bluff beds 
are older than that of Hatchitigbee bluff, this again is older than 
the Lisbon strata, which finally are overlaid by the Claibornian. 
In these consecutive beds we frequently find the same species, 
sometimes without apparent change, sometimes represented by 
slight variations and in some cases by strongly modified varia- 
tions, This material from Alabama, which I refer to, is in the 
collection of Mr. T. H. Aldrich—Ovso Meyer.

Among the samples of rocks 
during the soundings of the Talisman, mostly from depths of 
4000 to 5000 meters, the older metamorphic rocks are more gên- 
erally represented than the eruptive series. There were seventy- 
three specimens of limestones, sixteen of arkoses and nineteen of 
sandstones, the latter sometimes rich in remains of biotite and

and at Mpasa, north-west of Nyassa. These are referred by Rey-
